The Hobie kayak cart plugs right into the scupper holes of the current Hobie Outback, Sport, Mirage Tandem, Lanai, Maui, Adventure, Outfitter, Revolution, Odyssey, and Pro Angler.
It is so handy, I have not had any problems, It makes the getting there alot easier
I use this cart with an Ocean kayak Zest 2. It fits just right in the holes in front of the back seat. The wheels are very light and don't float so it is easier to slide under the boat in the water than the cart with bigger tires. But the narrow tires don't work at all on sand or gravel so I only used it on pavement and concrete ramps. It's really handy and light so is easy to use. But, it is not very durable. It is made of light weight steel tubes that are inset into each other and then tack welded. On the 39th usage the welds started coming apart. Now on it's 70 or so usage all the welds are seperated and the tubes disengage from each other unless I tie the pieces together with cord. Also the keeper pin on top has fallen apart several times and is a hassle to put back together with the bungie cord hidden inside the tube and only attached with simple compression between the pin and the plastic cap. The tube is chrome plated so I don't know if it can be rewelded. I wouldn't buy another one as I could make one myself cheaper and better...
These carts are a great design. They are easy way to just slip into scupper holes. However they have serious defect. The spot welds easily break. I have a fleet of Hobie kayaks that I rent. I depend on these carts for my customers. They fall apart and are in constant need of repair. New I had to have them re-welded as all the welds break. The caps and fittings all fell out causing damage to the kayak. Beware! If you use these carts they will not last long.
These wheels work fine. On sand or soft soil it gets much more difficult to pull, but it is still doable. I've had them for about 3 weeks and the locking pin came out of its plastic housing. I shoved it back in and I haven't had any more problems.
